Affective State Recognition Using Thermal-Based Imaging: A Survey

The thermal-based imaging technique has recently attracted the attention of researchers who are interested in the recognition of human affects dueto its ability to measure the facial transient temperature, which is correlated withhuman affects and robustness against illumination changes. Therefore, studieshave increasingly used the thermal imaging as a potential and supplemental solution to overcome the challenges of visual (RGB) imaging, such as the variation oflight conditions and revealing original human affect. Moreover, the thermal-basedimaging has shown promising results in the detection of psychophysiological signals, such as pulse rate and respiration rate in a contactless and noninvasive way.This paper presents a brief review on human affects and focuses on the advantages and challenges of the thermal imaging technique. In addition, this paper discusses the stages of thermal-based human affective state recognition, such asdataset type, preprocessing stage, region of interest (ROI), feature descriptors,and classification approaches with a brief performance analysis based on a number of works in the literature. This analysis could help beginners in the thermalimaging and affective recognition domain to explore numerous approaches usedby researchers to construct an affective state system based on thermal imaging.

The Oceanic Imagination: Affects, Surreal Images and Strings

The creative forces of affects are considered to be a mysterious power within our immanence. Although creators exist like lonely islands and may be more vulnerable to poor health, it is problematic to draw an inference that mental illness nourishes creativity. Artists, philosophers, and scientists have to struggle with chaos to create a new vision into their works. This paper argues that first, the creativity of affects is a mysterious power of our immanence, not nourished by pathology;second, the surreal images of curved and juxtaposed spaces by the artists resonate with the scientific experiments conducted by string physicists who propose the existence of multiverse with the possibility of 11-dimensional spaces. Therefore, the creators have shared the equally-important status as the singular beings in their different modes of lives. Deleuze’s and Guattari’s creative concepts of philosophy help improve the better understanding of the mysterious power of oceanic affects within our immanence. Thus, the general opinion that creativity and mental illness are infamously connected should be entirely re-questioned and re-examined.

Analysis of the Tourism Image of Urban Waterfront Nanjing City

The quantitative analysis method was used to measure the tourism image of Nanjing waterfront to make clear its composition.An evaluation method was also adopted in terms of cognitive image,affective image and the whole image,which may offer some references for the evaluation of other tourism images in urban waterfront of the same kind.

Image of Landscapes in Ancient Water Towns——Case Study on Zhouzhuang and Tongli of Jiangsu Province

Researchers in several disciplines and fields agree that the image establishing has both perceptual and affecfive evaluations. The paper comparatively analyzes the image of landscapes in ancient water towns held by 1619 tourists after the investigations of Zbouzhuang and Tongli of Jiangsu Province. Based on the elements of the image of urban landscapes, the perceptual/cognitive image of tourist landscapes in water towns is developed including path, node, landmark, important courtyard, district and edge. Particularly the important courtyard plays the great role on the perceptive image of tourists, however, the perceptual/cognitive images of the district and the edge are obviously weak. Meanwhile, the finding showed that the affective images of tourist landscapes in Zhonzhuang differ with those of Tongli by the method of paired comparison. The main reason is that the affective images are influenced by the impressive scenery spots. Furthermore, the commercialization of streets and pollution of rivers are easy to be functioned negatively.

The Central Role of Affect in Learning English as a Foreign Language

Affective Image Colorization

Colorization of gray-scale images has attracted many attentions for a long time. An important role of image color is the conveyer of emotions （through color themes）. The colorization with an undesired color theme is less useful, even it is semantically correct. However this has been rarely considered. Automatic colorization respecting both the semantics and the emotions is undoubtedly a challenge. In this paper~ we propose a complete system for affective image colorization. We only need the user to assist object segmentation along with text labels and an affective word. First, the text labels along with other object characters are jointly used to filter the internet images to give each object a set of semantically correct reference images. Second, we select a set of color themes according to the affective word based on art theories. With these themes, a generic algorithm is used to select the best reference for each object, balancing various requirements. Finally, we propose a hybrid texture synthesis approach for colorization. To the best of our knowledge, it is the first system which is able to efficiently colorize a gray-scale image semantically by an emotionally controllable fashion. Our experiments show the effectiveness of our system, especially the benefit compared with the previous Markov random field （MRF） based method.

Sustained attention in psychosis:Neuroimaging findings

To provide a systematic review of scientific literatureon functional magnetic resonance imaging(fMRI) stud-ies on sustained attention in psychosis. We searchedPubMed to identify fMRI studies pertaining sustainedattention in both affective and non-affective psycho-sis. Only studies conducted on adult patients using asustained attention task during fMRI scanning wereincluded in the final review. The search was conductedon September 10 th, 2013. 15 fMRI studies met our in-clusion criteria: 12 studies were focused on Schizophre-nia and 3 on Bipolar Disorder Type Ⅰ(BDI). Only halfof the Schizophrenia studies and two of the BDI stud-ies reported behavioral abnormalities, but all of themevidenced significant functional differences in brain re-gions related to the sustained attention system. Alteredfunctioning of the insula was found in both Schizophre-nia and BDI, and therefore proposed as a candidate trait marker for psychosis in general. On the other hand, other brain regions were differently impaired in affective and non-affective psychosis: alterations of cingulate cortex and thalamus seemed to be more common in Schizophrenia and amygdala dysfunctions in BDI. Neural correlates of sustained attention seem to be of great interest in the study of psychosis, highlight-ing differences and similarities between Schizophrenia and BDI.

Affective rating ranking based on face images in arousal-valence dimensional space

In dimensional affect recognition, the machine learning methods, which are used to model and predict affect, are mostly classification and regression. However, the annotation in the dimensional affect space usually takes the form of a continuous real value which has an ordinal property. The aforementioned methods do not focus on taking advantage of this important information. Therefore, we propose an affective rating ranking framework for affect recognition based on face images in the valence and arousal dimensional space. Our approach can appropriately use the ordinal information among affective ratings which are generated by discretizing continuous annotations.Specifically, we first train a series of basic cost-sensitive binary classifiers, each of which uses all samples relabeled according to the comparison results between corresponding ratings and a given rank of a binary classifier. We obtain the final affective ratings by aggregating the outputs of binary classifiers. By comparing the experimental results with the baseline and deep learning based classification and regression methods on the benchmarking database of the AVEC 2015 Challenge and the selected subset of SEMAINE database, we find that our ordinal ranking method is effective in both arousal and valence dimensions.

感知原真性对游客情感形成的影响机制研究以开平碉楼为例

游客在遗产地感知原真性后是否以及怎样引发情感的形成,有关研究相对缺乏。同时,地方依恋与亲密关系理论是研究情感的重要理论,二者存在许多交叉域,但少有研究结合二者进行探讨。在文化遗产旅游背景下,文章以地方依恋和亲密关系理论为基础,选取情感体验、情感形象和情感依恋这一系列反映情感形成过程的构念,探究感知原真性如何影响游客情感的形成(内在作用机制),并对比有形文化遗产与无形文化遗产的感知原真性在机制中的不同表现。结果表明:(1)情感体验、情感形象在感知原真性与情感依恋之间发挥链式中介作用;(2)情感体验在感知原真性与情感形象之间发挥完全中介作用;(3)相较于有形文化遗产,无形文化遗产的感知原真性对游客情感形成的正向影响更强烈。
